Me and my daughter went to the range today with her 30-30 to make final adjustments before deer season. i shot first and the first 2 were under 1" at 100yds. she shot the next three at just over 1". seemed we were right there. i set up a full size deer target at 130yd. both of us were shooting and neither of us could get a group. I'm talking like 5-6" and all were high. dead on at 100yds and no grouping at 130yds. same loads, same bench rest, same everthing. let barrel cool, and shot a few as fast as i could. shot a few more back at the 100yd target and they were right back where we started.
anybody ever heard of this? ideas?
